EDWIN E. FREDERICK, OF BRIDGEVILLE, PENNSYLVANIA.

GLOBE-HOLDER.

To all whom it may concern:

Be it known that I, EDWIN E. FREDERICK, a citizen of the United States,and residing in the borough of Bridgeville, in the county of i-illeghenyand State of Pennsylvania, have invented or discovered new and usefulImprovements in Globe-Holders, of which the following is aspecification.

My invention consists in certain new and useful improvements in springholders for globes, shades and similar articles, and is especiallyintended for use in connection with depending lights, such as invertedincandescent gas-lights.

The object in view is to improve both the quality and appearance of thatclass of devices, and also to make the same less expensive ofmanufacture.

In the accompanying drawings, Figure 1 is an elevation of an invertedgas-light fitted with my invention; Fig. 2 is an inverted plan view ofthe same; Fig. 8 is a reduced plan view of the wire clamp removed fromthe holder, and Fig. 4 is a broken inverted plan view, similar to Fig.2, but showing the spring fingers of the wire clamp expanded to admit ofthe insertion or removal of the globe.

The following is a detailed description of the drawings:

A is an inverted incandescent gas-light wherein 1 is the gas check, 2the mantle support and 3 the depending canopy from which the globe is tobe suspended. Said canopy is usually stamped of sheet brass or othersuitable material and is provided with a depending annular flange t. 5-5are the ports in said canopy for the escape of the products ofcombustion. The flange 4 is provided with a circumferential seat orrecess on its inner surface, formed by rolling in said flange theexterior bead 6.

The clamp member is formed by bonding up a length of stout resilientwire, 7, into an annulus having overlapping ends. The said ends are bentinwardly and then outwardly to form the inwardly extending springfingers 88. The body of the annulus is provided with two inwardlyextending loops forming teeth 99. The body of the annulus is sprung intothe seat formed by the bead 6 and firmly maintains its position therein,as shown in the draw ings. The body of said annulus is concealed in saidseat while the teeth 9-9 and the spring fingers 88 extend into theinterior Specification of Letters Patent.

of the fixture. The ends of the wire 7 extend through slots 10-10 in theflange 4t and are formed, exterior to said flange, into finger loops11l1.

The flaring neck flange of the globe is supported by the teeth 99 andthe spring fingers 88 which press the globe against said teeth. Topermit the insertion or removal of the globe, the end loops ll-l1 arepressed toward each other by the fingers of the hand, thus drawing thespring finger outwardly toward the flange 4, as shown in Fig. 4, andpermitting the passage of the neck of the globe through the annulus. Theonly portions of the wire which move during such operation are the twofingers 88, the body of the annulus remaining stationary and immovablein its seat formed by the bead 6.

The advantages of my invention are manifold. Among them may be mentionedthe following: The annulus maintains its position in the flange 4:without the aid of a holding device such as a rivet or the insertion ofa secondary loop of the wire in a slot cut in the canopy flange. Thisgreatly cheapens the cost of manufacturing the goods which are sold at asmall profit under close competition. It also preserves the symmetry ofthe fixture, no rivet heads, slots or protruding loops existing to marits appearance. The body of the annulus being stationary, the centeringof the globe in relation to the canopy is more accurate, the teeth 9-9being fixed and the globe being pressed against the same by the springfingers. As the relatively short fingers are alone expandible, thedevice is more readily and easily operated than would be the case if theentire annulus expanded or contracted. In case the entire annulusexpanded and contracted when a globe is inserted or removed, it would benecessary to provide additional means for securing the annulus in placein the canopy. WVhere the entire annulus expands and contracts thesupport is at two points, the center of the annulus and the slotsthrough which the spring fingers pass through the canopy. This isinsufficient to prevent the intermediate portions of the annulussagging, thus holding the globe loosely and permitting the wire toappear below the canopy flange. The globe therefore rattles and islikely to fall. Again in my device the wire annulus is protected by itsseat from the direct heat so that its temper is not destroyed, the basesof the fingers 88 being protected by the flange 4.

lVhat I desire to claim is 1. In a globe holder, a depending annularflange provided with an interior circumferential seat and a pair ofadjacent slots, a length of wire bent up into an open annulus having itsbody held against flexing in said seat and pro-vided with fixed inwardlyextending teeth, and overlapping spring fingers formed of the endportions of wire extending inwardly and cooperating with said teeth tosupport the globe, the extreme ends of said wire extending through saidslots to the exterior of said flange to form handles whereby saidfingers may be expanded, for the purposes described.

2. In a globe holder, a depending annular flange provided with aninterior circumferential seat and a pair of adjacent slots, a length ofresilient wire bent up into an open annulus and sprung into said seatand held against flexing therein, said body being provided with fixedinwardly extending teeth, annular overlapping spring fingers formed ofsaid wire at the ends of the body extending inwardly to cooperate withsaid teeth to support the globe and adapted to be expanded outwardly torelease the globe, and

nulus being sprung into said depression and held innnovably in saiddepression when said overlapping ends are compressed together, inwardlyextending teeth formed by loops in the body or" said annulus, theoverlapping ends of said annulus being first bent to form inwardlyextending spring fingers, adapted to cooperate with said teeth to gripthe globe, and then bent sharply in an outward direction to pass throughsaid slots to fol-n1 operating handles, substantially as and for thepurpose set forth.
